  • Publication number: 20200186299
    Abstract: A method comprises transmitting from a user device information on first and second hybrid automatic request acknowledgement bits and a scheduling request in a same transmission time interval. The information on said first and second hybrid automatic request acknowledgement bits and said scheduling request are transmitted via first and second physical resource blocks using one or more resources of a set of resources. At least one of the resources of the set of resources differs from the one or more resources of the set of resources used to transmit information on the first and second hybrid automatic request acknowledgement bits when there is no scheduling request.

  • Patent number: 10652936
    Abstract: Methods, apparatuses, systems, and computer program products for transmitting/receiving scheduling assignment(s) (SAs) are provided. One method is directed to including a short version of a target ID (i.e., short ID) in a SA. The method may also include transmitting the SA including the short ID to one or more monitoring UE(s). The monitoring UE(s) may then compare the short ID to target ID(s) being monitored. The corresponding data from the SA may be decoded if there is a match between the short ID and any of the target ID(s).

  • Patent number: 10587493
    Abstract: Various communication systems may benefit from techniques and systems for resource allocation. For example, communication systems of the third generation partnership project may benefit from device to device discovery resource allocation methods and systems. A method can include determining that downlink data transmission may cause conflict between uplink control channel transmission and device to device discovery signal transmissions or that uplink shared channel transmissions may conflict with device to device discovery signal transmissions; and requesting a user equipment to report device to device discovery needs based on the determining.

  • Publication number: 20190239251
    Abstract: Systems, methods, apparatuses, and computer program products of preamble sequence management for contention based access are provided. One method may include a user equipment sending a contention based access (CBA) request message, such as a random access procedure (RACH) message, to a network node (e.g., a base station or eNB). The CBA request message may include an indication that the user equipment wants to obtain a preamble for CBA data transmission and is not for full network access. The method may then include receiving an allocation of a preamble for CBA from the network node.

  • Patent number: 9980243
    Abstract: Systems and techniques for synchronization between in-coverage and out-of coverage user devices. A base station configures in-coverage and out-of coverage synchronization signals and configures user devices to recognize synchronization signals as in-coverage or out-of-coverage. An in-coverage device furnishes an in-coverage synchronization signal upon detection of an out-of coverage signal, and may continue to furnish the signal upon continued detection of an out-of-coverage signal that is not synchronized to the network. An out-of-coverage device may receive and synchronize to an in-coverage signal if available, or an out-of-coverage signal if available, or may generate and transmit its own out-of-coverage signal if no in-coverage or out-of-coverage signal is available.
